New Orleans Saints tailback Reggie Bush limped through the New Orleans Saints locker room on Friday, but he wasn't on crutches and didn't have any cast or brace on his broken right fibula.

The early prognosis for Bush was that he's expected to miss four to six weeks after suffering the broken leg during Monday night's victory at San Francisco. But Bush said as painful as the injury was, it was a small fracture and that no cast is needed for it to heal. He is optimistic he can beat that estimated timetable.

"It's frustrating," Bush said of the latest in a string of injuries that have interrupted his NFL career. "But I think it will be less time than everybody thinks."
